Driver-assistance systems and fully autonomous vehicles could address the global challenges of traffic congestion and reduced road capacity. Although the field of autonomous transportation is growing rapidly, system complexity and cost have delayed progress. This project attempts to mitigate these issues through the development of a scale model robot that utilizes the sensors of smartphones for autonomous navigation and collision avoidance. Designing a model robotic system is simpler and more cost-e?ective than developing one for a full-sized vehicle. This project investigates the possibility of using smartphones sensors as a viable alternative to high-end, expensive sensors. The system utilizes the Orca Robotics software framework, which provides a library of modular and customizable components. The results from this study suggest that integrating smartphone sensors is much more challenging than using standalone devices. Further work is needed to confirm the feasibility of using these sensors. Ideally, as smartphones continue to improve in computational power and sensor accuracy, it will be possible to use them as integral components in autonomous systems.

Simulation of electronic transport in nanoscale devices plays a pivotal role in shedding light on underlying physics, and in guiding device-design and optimization.The length scale of the problem and the physical mechanism of device operation guide the choice of formalism. In the sub-20 nanometer regime, semi-classical approaches start breaking down, thus necessitating a quantum-mechanical treatment of the electronic transport problem.

In this position paper, we present the research initiative for a precision timed (PRET) infrastructure, consisting of languages, compilers, and microarchitectures, where timing is a correctness factor. In particular, the timing semantics in models and programs must be preserved during compilation to ensure that the behavior of real systems complies with models. We also outline new research and design challenges present in such an infrastructure.

I present a method for decreasing the duration of artifacts present during intracortical microstimulation (ICMS) recordings by using techniques developed for digital communications. I use a Zero-Forcing Equalizer (ZFE) to shape a stimulus pattern with the aim of reducing artifact length. The results find that using the ZFE stimulus has the potential to reduce artifact duration by more than 70%. Continuing work and current considerations for the hardware implementation of the equalizer are presented.

In many simultaneous localization and mapping (SLAM) systems, it is desirable to exploit the fact that the system is traversing though a previously visited environment. Once these locations, commonly known as loop closures, have been detected the system must be able to both compute and verify the relative transformation between proposed locations. In this thesis we present two independent algorithms, using 2D LiDAR scanners, for robustly computing the transformation between arbitrary locations with overlapping geometry and validating the resulting transforms. First, a scan matching algorithm based on a genetic search and a fractional distance metric is presented. Secondly, two metrics are proposed to verify the recovered transforms. Through experimental results the proposed algorithms are shown to robustly estimate and validate loop closure transformations for both manually and automatically defined candidates. Finally, the proposed algorithms are demonstrated in an end-to-end SLAM framework.

In this thesis, a promising approach using chemically synthesized nanomaterials is explored to overcome various obstacles current technology faces in this field. Here, we use chemically synthesized semiconducting nanowires (NWs) including group IV (Si, Ge), III-V (InAs) and II-IV (CdS, CdSe) NWs, and semiconductor-enriched SWNTs (99 % purity), and developed reliable, controllable, and more importantly uniform assembly methods on 4-inch wafer-scale flexible substrates in the form of either parallel NW arrays or SWNT random networks, which act as the active components in thin film transistors (TFTs).

The semiconductor industry has relied on accurate device models for analyzing, predicting and innovating integrated circuit design.Multi-gate MOSFET device architectures like FinFETs are beginning to replace their planar MOSFET counterparts at the 22 nm technology node to enable continued technology scaling. Vertical cylindrical gate (CG) MOSFET are touted to replace planar MOSFETs as the memory device for DRAM and NAND Flash offering increased area density.

Fully printable flexible transistors are key to high throughput production of flexible electronics at low cost. In this work, the advantages of an inverse gravure printing system and the solution-processing of 99% semiconductor enriched single-walled carbon nanotube (SWCNT) solutions are combined to fabricate fully printable SWCNT flexible top-gated thin-film transistors. The fully printed transistors exhibit high performance with mobility and on/off ratio up to 7.8 cm2/Vs and 104 while remaining stable when bent to 1 mm radius of curvature. With the transistors’ high performance, throughput, uniformity, flexibility and stability, we have demonstrated the potential for our printing process scheme to serve as the backplane for future scalable, low cost, high throughput, flexible electronics applications.
